Setting up a new CachyOS machine

Install Nix

Install the Nix package manager:

sh <(curl --proto '=https' --tlsv1.2 -L https://nixos.org/nix/install) --daemon

Enable experimental features by adding to /etc/nix/nix.conf:

experimental-features = nix-command flakes

Get configuration

Clone the home.nix repository:

git clone https://github.com/fnune/home.nix ~/.home.nix
cd ~/.home.nix

Apply Home Manager configuration

From the ~/.home.nix directory:

nix run home-manager/release-25.05 -- switch --flake "."

This downloads over 20GB of packages.

To switch later, you can use nh:

nh home switch .

Set up locales

Add these locales to /etc/locale.gen:

en_US.UTF-8 UTF-8
en_DK.UTF-8 UTF-8
en_GB.UTF-8 UTF-8
de_DE.UTF-8 UTF-8

Generate locales:

sudo locale-gen

Configure /etc/locale.conf:

LANG="en_US.UTF-8"
LANGUAGE="en_US:en"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"

LC_TELEPHONE="de_DE.UTF-8"

Configure boot splash

Plymouth is pre-installed in CachyOS. Configure theme:

sudo plymouth-set-default-theme spinner
sudo mkinitcpio -P

Fix some Flatpaks

To make Flatpaks work more seamlessly with the host system:

flatpak override --user com.slack.Slack --socket=wayland --env=ELECTRON_OZONE_PLATFORM_HINT=auto

Install browser policies

Install system-wide browser policies for Firefox and Chromium:

install-browser-policies

This installs:

• Firefox policies to /etc/firefox/policies/policies.json
• Chromium policies to /etc/chromium/policies/managed/policies.json

Restart browsers and verify at about:policies (Firefox) or chrome://policy (Chromium).

Tuxedo InfinityBook hardware setup

For the Tuxedo InfinityBook Pro 14 Gen9, additional setup is required:

Disable secure boot

The ethernet driver requires secure boot to be disabled in BIOS/UEFI.

Add kernel parameter

Edit your boot entry file:

sudoedit /boot/loader/entries/linux-cachyos.conf

Add the parameter to the options line:

options root=UUID=<redacted> quiet acpi.ec_no_wakeup=1

Install ethernet driver

sudo pacman -S linux-cachyos-headers
